As for how Culpo chooses her styles, the former beauty queen reveals it's not that much of a choice.

"For Fashion Week, obviously the designers want you to showcase their work, so they'll send you their clothes," she revealed. "You really don't get that many options because there are a lot of people coming to the shows, and there's a limited amount of clothing that they're going to be able to provide. So you work with a stylist usually, or you just kind of figure out what would work best."

"Usually there's a lot of tailoring involved because they're not quite fitted yet. They're not ready to wear, they're just straight off the runway, or not even shown in collections yet, so it's usually a really, really big process of tailoring," she explained, adding that she had "probably 15 hours" of fittings for NYFW. "Nothing ever fits the right way."

"You're going to run into everybody during Fashion Week. Everybody's here," Culpo said, adding that she's not even scared of a run-in with exes Nick Jonas or Tim Tebow. "I have no fears during Fashion Week. I change in cars -- no fears."

And with a final wardrobe change, and a new set of bangs, which only "lasted about one hour," Culpo headed off to her final event of the day in a stunning white Kaufman Franco gown.
